Abstract: A track pin may comprise a body that includes a generally cylindrical configuration defining an axis of rotation, a circumferential direction and a radial direction, the body defining a first end, a second end and a peripheral surface extending from the first end to the second end. The peripheral surface may include a first lobed portion spaced axially away from the first end and the second end and including a series of convex arcuate segments and concave arcuate segments joined to each other tangentially, forming an undulating surface.

Abstract: In one instance, disclosed herein is a computer-implemented method for monitoring an undercarriage of a track-type machine, the computer-implemented method comprising: accessing a reduced order model (ROM) corresponding to the track-type machine; receiving an estimated wear level of at least one undercarriage component of a track-type machine and machine signal data generated by the track-type machine; generating an updated estimated wear level of the at least one undercarriage component using the estimated wear level, the machine signal data, and the ROM; and comparing the updated estimated wear level of the at least one undercarriage component to a wear level threshold.

Abstract: A system for providing casting design advisement for designing a cast component is provided. The system includes an integrated design environment, the integrated design environment receiving a concept design for the cast component, the concept design being user-modifiable. The system also includes a plurality of design advisory modules, the plurality of design advisory modules determining physics models associated with the concept design for the cast component and providing advisement analysis for the concept design based on the physics models. The system includes a design rule logic solver for receiving concept design features associated with the concept design and comparing the concept design features with stored casting design rules to determine a geometry modification guide.
